'IENTER CLIP Application mea December 10,71929. serial No. 41ans?. s

This invention relates to an improved construction of tenter clip; andhas for its object to provide a clip of this character which is so constructed that the jaw is permitted to drop freely and quickly to bite the fabric when the vedgel of thefabric is withdrawn from beneath the jaw control member.

i A. further 'object of the invention is the provision of a jaw controlmembervwith a l0 greatly elongated bearing sleeve on which it is pivotally hung to prolong the working life of the control member and also to lreduce the cramping of the swinging movement of the control member due to action upon it of the travelling work on which it rests.

A still further object of the invention isV to provide al plurality of feeler'fngersso as to distribute'the 'weight of the control mem-q ber andthe jaw upon the travelling goods 2.0 so that the weight of these members is 4less likely to forcerthe goods `into the slotsbeneath theseiingers, particularly when the goodsare thin or delicate.

A still further object of this invention is to so construct'the/control member that a minimumamount of machine operations will be required for shaping andl mountingthe same onlits bearing member. v With these and other objects in view, the invention lconsistsyof certain novel .features of construct-ion, as willbe more fully dev scribed. and. particularly. pointed out in the appended claims.
